BACKGROUND OF THE INVENTION

(1) Field of the Invention

The present invention relates to a mud/sludge removing device, and more particularly, to a removing device for removing mud/sludge under water and efficiently collecting the mud.

(2) Description of the Prior Art

The techniques for removing mud or sludge from bottom of rivers and sea are developed along with the requirements of mining, maintenance of beaches, under-water piping engineering or land reclamation. The conventional equipments for removing the mud are equipped with a scooper, a chain, a driller, a rack and some of which is cooperated with a suction device. However, all of the mud/sludge devices have high maintenance fee and high wearing, and can only be used in specific areas. The operation is restricted by depth of water and may contaminate the water.

CN 1235652 discloses a device which has a case merged in the water and is connected with suction tubes which remove the water in the case, a pump which uses the level difference between the water level in the case and the water level outside of the case, and a tank removably connected to the suction tubes. The water in the case is removed by the pump so as to form the space in the case, the level difference causes the water to flow so as to suck the mud/sludge from the suction tubes into the tanks. The device is helpful to remove the mud/sludge from lakes, bays, or reservoirs, but it also has high maintenance fee and consumes high energy.

Taiwan Utility No. M386319 discloses a device which has a cage with a pimp and multiple tubes, the pump ejects water toward the underside of the cage and the tubes are located in the case. The outlets of the tubes are located at the underside of the cage and each tube is connected with high-pressure air tube.

Taiwan Utility No. M387107 discloses a device which has a water inlet tube which is pivotably connected to a water injection device, an air injection device connected to the center of the underside of the water inlet tube by multiple radial rods, and an air inlet tube extending through the water inlet tube and communicating with the air injection device. The water inlet tube and the air inlet tube extend toward the water level so as to respectively connect with the high-pressure water source and the high-pressure air source such that the water injection device and the air injection device are rotated simultaneously and eject water and air. The device only disturbs the mud/sludge, the collection device is not mentioned. Besides, the related such as motor and pump are heavy and bulky and require significant oil and electric power.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1 to 4, the mud removing device of the present invention comprises a case 1, a suction tube 2, multiple injection tubes 3, multiple weights 4 and a working station 5. The case 1 has a curved space 11 and an opening which communicates with the space 11. The first end of the suction tube 2 extends through the center of the case 1 (recessed and curved top of the case) and communicates with the space 11 via a suction hole 23 of the first end of the suction tube 2. The suction hole 23 has a filtering net 24 connected thereto. The second end of the suction tube 2 is connected to the working station 5 via a hose 21. The suction tube 2 has rings 22 connected thereto which are connected to a cable 521 of a crane 52 of the working station 5.

Multiple injection tubes 3 are connected to the case 1 and extend through the case 1. The first end of each of the injection tubes 3 extends through the case 1 and is inserted into with the space 11. The second end of each of the injection tubes 3 are connected to the working station 5 via a high-pressure water tube 31. Multiple injection tubes 3 are evenly located close to the periphery of the opening so as to form respective injection outlets 32. The case 1 has multiple holding units 41 connected to outside of the case 1 and each of the holding units 41 has two parallel holding members 411. Each holding member 411 has a slot 412. There are multiple weights 4 and each are a plate, two sides of the weight 4 are inserted into the slots 412 of the two holding members 411. The number of the weights 4 can be adjusted according practical needs. The working station 5 is connected to the hose 21 and the high-pressure water tube 31. Pump or the like located in the case 1 is used to generate suction force via the hose 21 and high pressure water is introduced into the high—pressure water tube 31. When in use, the working station 5 is carried by a floating carrier 51 with power such as a boat and a came 52 is provided on the working station 5. The crane 52 has multiple cables 521 so as to drive hooks 522 which hook the rings 22. The case 1 is then merged into the water by the crane 52.

The high pressure water is introduced into the injection tubes 3 via the high-pressure water tubes 31 so as to form water blades via the injection outlets 32 to flush the mud located beneath the opening of the case 1. The mud is then sucked by the suction holes 23 of the suction tube 2. The sucked mud is filtered by the filtering net 24 and then sucked to the working station 5. By operation of the crane 52, the case 1 can be put to different depth in the water.

Furthermore, because the water pressure applied to the mud which has higher density and hardness at deeper bottom of the river or reservoir, the power needed to flush the mud is increased, so that multiple injection tubes 3 on the case 1 are equipped to flush the mud in different depths to increase the efficiency of the removal of mud.

While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
